04 GT running rich / loading up

Runs fine during idle. Smooth. Problem is that it acts like it's dumping fuel and running on 6 cly when you get in the gas (anything past 3k RPM). Plugged in to reader, and showing good MAF, o2, and CTS readings. I changed TB/plenum and intake about 8 months ago and added MIL eliminators, but this problem just started within the past week. I have disconnected battery and reset computer, but still having no luck. So, I'm going to stand here and scratch my head some more.....

When was the fuel filter changed last? Check all the connections on your intake. Kind of weird its not throwing any codes.

Just because mafs can be a batch. Pull it out and look at it and she if it's dirty at all across the resistors. If so spray a little brake clean on them (carefully) and see how it runs after that. Dirty mafs can cause stupid intermittent problems without throwing codes

Sounds like a secondary ignition issue. Coil packs could be bad. Typically a miss under load is a secondary ignition issue. In my experience.
